Hmm. I can easily see this producing incomprehensible code when spread
across large systems. To wit, those developers used to "0 means false"
semantics seeings a scalar that they just know has a 0 in it and
wondering why the branch isn't doing what they know it should.
This will have to be addressed using a coding convention of some sort,
I suppose. What's the verbose way to query the "is true" property of a
thingy?
